Display the source file name

[nedbat]

When I don't know which file I am looking at, I use "L" to see the file name. Pudb could display the name in the title of the source pane.

[inducer]

That's a whole row of characters down the tube though. I appreciate every row not occupied by UI, especially on size-constrained displays. Plus I'm not that often disoriented about where I am, but then I'm mostly debugging my own code. I could see it as an option, maybe.

[nedbat]

I wasn't going to use a new row, I would add it to the very top row, which has a lot of space left.

[asmeurer]

The top row seems pretty full if you have a smaller terminal (isn't the default on most systems 80 characters wide?). The row the says "command line" is pretty empty, though.

[inducer]

Agree that the top row is pretty full. That "command line" line should probably be removed (rather than cluttered up more).

[asmeurer]

Then again, if you run PuDB fullscreen (like I do and I'm guessing @nedbat does) there is plenty of room at the top. So it could be added there, but only visible for people willing to make their terminals wide enough.

[inducer]

That'd be good, but it's a little nontrivial to achieve in Urwid. (i.e. you're writing a custom Widget at that point)

[nedbat]

This might be controversial, but I don't think the top line needs as much help as it offers. "PuDB - ?:help" would be enough.

[inducer]

I could go along with that.

[asmeurer]

I mean only visible in the sense of what it already does now (truncate the top line).

[asmeurer]

Oh nevermind, it doesn't truncate. I misremembered.

I agree with @nedbat about preferring the top line to only have the "? - help" tip, and to include the current file name/path. I would suggest by default it display N chars from the end of the abspath of the current filename, where N is determined by an algorithm fed by a $COLUMNS from the shell, plus sidebar_width from the current pudb.conf settings. I prefer this solution to peer into the stack window for current filename.

Even as an option would be great - jumping around in large codebases I frequently have to open the L dialog just to see where I am, would be great if that could be seen at a glance

[dkao1978]

Having an option for this would be amazing. Anyone who's navigating up and down the stack will appreciate this. This is especially useful if you're trying to debug inheritance problems in a large code base.

"L" does not work in the Stack so you have to go back and forth between the stack and the main window to see which file you're looking at.

This is fantastic idea and love the filename being displayed!

I am experimenting with this and at a glance it looks quite easy.
The content of the top row is in this caption variable. We can get the current filename from DebuggerUI.source_code_provider.get_source_identifier() if I'm not mistaken.

From there other things like dynamic caption length computed from $COLUMNS, this feature being optional,... can be done quickly.
